The fired Balch Springs police officer who shot and killed a 15-year-old in a car leaving a party has been charged with murder, law enforcement officials confirmed to FOX4.

The murder warrant for Roy Oliver was signed Friday afternoon by a Dallas judge. Oliver has not yet been arrested but is expected to turn himself in with his attorney.

Jordan Edwards, a Mesquite High School freshman, was shot while he was in a car that was leaving a party Saturday night.

Oliver claimed he was investigating a call about underage drinking when Edwards and his brothers allegedly aggressively backed towards him in a car. But his body camera footage told a different story and police were forced to take back that version of events on Monday.

Throughout the week pressure has been building for a murder charge against Oliver. The Texas Legislative Black Caucus joined other voices Thursday in calling the shooting a murder and wanting Oliver arrested.

“It really is murder at the end of the day,” said State Rep. Helen Giddings (D-Duncanville).
